' In treat Britain March 22, 1938 16 Claims. (01. 12-14) This invention relates to lasting machines, and

more particularly to end-lasting wipers for use in such machines. The invention is herein'illustratedas embodiedin wipers intendedto be utilized in a heel-endlasting machine of the character disclosed in United States Letters Patent No. 1,949,539, granted on, March 6, 1934 upon an application of Joseph Gouldbourn, Fred Ricks, and William T. B. Roberts, but it is not limited to machines of that particular "character or to distinguished from the toe ends.

The wipers disclosed in the above-mentioned" Letters Patent ha'vebeen modified heretofore, as k disclosed in United States Letters Patent No.

2,082,837,granted on June 8, 1937 upon an application of Harold Lane and John W. Pratt, "to provide them at their forward ends (1. 'e'.,'the ends nearest the shank portion of the shoe) with wip ing members which are yieldable laterally of the shoe'relatively' to other wiping portions .of the wipers, so that the wipers may be closed inwardly as far as desired without danger of damage to the machine by reason of interference between their forward end portions. Such a construction is particularly advantageous when, as disclosed in the last-mentioned Letters 'Patent, the wiping edges of the forward endportionsof the wipers are curved inwardly lengthwise of the 'shoe to prevent the margin 'of' the upper. from being crowded unduly forward in the wiping operation and operate uponp'ortions of the upper extending somewhat forwardly of the heel seat where the bottom ofthe shoe is comparativelynarrow. An object of the present invention is to. insure that such yieldable end-wiping members will not yield too soon in the Iwiping operation by reason of pressure of the shoe materials against them, and therefore not wipe inwardly as faras'they should the portions of the margin of the upper which they engage. For the purpose'in view, as herein shown, there is associated with each of the yieldable wiping members a device which looks it positively against yielding until the wipers are near-the limits of their inward wiping movements a over the shoe bottom, whereupon the locking devices release the yieldable wiping members. and thuspermit them to yield during furtherinward movements of the main portions ofjthe wipers. The wipers disclosed in boththe above-mentioned Letters Patent are provided with forward end portions which may yield heightwise of the shoe relatively. to other wipingportionsthereof in response to,' pressure of the shoe upon them if, for, example, their end portions should encounter in the wiping operation the lip of a welt shoe insole or should wipe the upper over a portion of an insole which isv curved heightwise of the shoe from the heel seat forwardly in th'emanner characteristic of some shoes provided with heels;

In the wipers disclosed in Letters Patent No. 2,082,837 such yieldable end portions include the above-mentioned laterally yieldable wiping members. In accordance with'a further feature of the present invention, the wipers herein shown are provided with end portions which are yieldable heightwise of the shoe by swinging movements relatively to the mainportions of the wipers, instead of by rectilinear movements as heretofore, so as to preserve a substantial continuity between the wiping faces of the'end portions and the main portions of the wipers and thus insure adequate pressure on the margin of the upper immediately adjacent to the main portions while avoiding any danger of marking the upper where these portionsterminate. 1

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more,

particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

With reference first to the construction shown in Figs. 1 to 6, inclusive, the wipers comprise blocks I and 3 which serve as the main upperengaging portions thereof, substantially as in the construction shown in Letters Patent No. 2,082,837, these blocks being supported and operated in the manner fully disclosed in Letters Patent No. 1,949,539. Fastened on the forward ends of these blocks are end pieces 5 and "I, each secured to its block by a screw (not shown) and further positioned by a dowel pin ll, these end pieces being detachable to adapt the wipers better for use on comparatively small shoes. Formed in each of the detachable end pieces are two tack driver passages, one of which is shown in dotted lines at [3 in Fig. 4, similar to driver passages in the wiper blocks, and also tack-supplying passages leading to these driver passages, one of the tack-supplying passages being shown in dotted lines at l5 in Fig. 4. The driver passages l3 have in them spring-pressed balls, one of which is shown at l! in Fig. 4, which support the tacks in positions to be driven by the corresponding tack drivers.

In the construction herein shown each of the detachable end pieces 5 and 7 has secured to it by a screw l9 a plate 2| provided with an arcuate guide 23 which lies in a corresponding guideway formed in a wiping member 25 arranged to serve as a continuation of the main wiping portion of the wiper, the guide and guideway being curved about an axis, indicated at 2? in Fig. 5, lying near the forward end of the corresponding wiper block I or 3 and near the plane of the wiping face of the block. The wiping member 25 has secured thereon a plate 29 engaged by one end of a spring 8i the other end of which lies in a bore in the end piece 5 or I. The spring normally holds the plate 29 against a face 33 on the end piece, with the member 25 in a position in which its wiping face is in the same plane as the wiping face of the wiper block, but permits the member 25 to swing heightwise of the shoe about the axis 27 in response to pressure of the shoe materials against it. The wipingmember 25 corresponds to the member il shown in Letters Patent No. 2,082,837 and has pivoted .to it by a normally vertical stud 35 a wiping member 31 integral with the stud, this member corresponding to the member 39 shown in the lastmentioned Letters Patent. The wiping member 3'! is normally positioned with a face ll thereon in engagement with a face 53 on the member 25 by a spring d5 one end of which lies in a recess 41 formed in a portion 59 of the member 25 and the other end in a recess 51 in the member 3?. The wiping member 3'! may yield laterally of the shoe about the axis of the stud 35 against the resistance of the spring 45, and since the stud 35 is carried by the wiping member 25, both the members 25 and 37 are yieldable as a unit heightwise of the shoe about the axis 21. The above-mentioned plate 29 extendsinto a recess in the wiping member 37 to hold this member from falling, while permitting it to swing about the axis of the stud 35.

Mounted in a recess in each of the wiping members 3'! is a pawl 53 pivoted on a pin 55. This pawl is arranged normally to lie in a notch 59 formed in the portion 48 of the wiping member 25, and thus to prevent the wiping member 3? from yielding about the axis of the stud 35. The pawl has a tail portion 5i engaged by one end of a spring 63 the other end of which lies in a recess in the wiping member 37, this spring normally holding the pawl in the notch 59. When the wipers are closed inwardly toward each other the wiping members 3'! are therefore first held by the pawls 53 from yielding laterally of the shoe relatively to the members 25 and the wiper blocks i and so that their inwardly curved edges 65 wipe the margin of the upper inwardly over the insole in an unyielding manner. Insurance is thus afforded that the members 31 will be carried inwardly over the shoe bottom as far as is desirable. Near the end of the closing movements of the wipers, however, the tail portions 6! of the pawls 53 are carried into engagement with each other, whereupon the pawls are swung out of the notches 59 as the wipers continue their inward movements, thus permitting the members 31 to yield and to remain stationary during further movements of the wiper blocks and the wiping members 25. The swinging of the pawls in response to the pressure of their tail portions 6! against each other is limited by engagement of the tail portions with shoulders 61 on the members 3'1. If in the course of the wiping operation the wiping members 3'! should encounter the lip of a welt shoe insole or should move inwardly over an insole curved at the shank portion in the manner hereinbefore described, these members, together with the members 25, may yield heightwise of the shoe about the axes 21 against the resistance of the springs 31, the positions of these axes being such that in that event substantial continuity is maintained between the wiping faces of the members 25 and the wiping faces of the wiper blocks. Portions of the margin of the upper extending forwardly beyond the wiper blocks will accordingly be wiped over the insole with eifective pressure and without any danger of objectionably marking the upper at the junctions of the wiper blocks and the members 25.

The embodiment of the invention illustrated in Figs. '7, 8 and 9 is particularly adapted for use in operating on womens shoes which do not require that the detachable wiper end pieces extend so far forwardly as in the case of mens shoes, or that more than a single tack be driven from each of the detachable end pieces. Each of these end pieces in this embodiment comprises two parts II and 73 secured together and to the forward end of the corresponding wiper block by a screw (not shown) passing through holes 15 (Fig. 9) in the parts, a dowel pin 71 being further provided for positioning the parts in proper relation to the wiper block. The part ?3 has formed in it an arcuate guideway 19 the axis of which, indicated at Bl in Fig. 8, corresponds in location to the axis 21 of the first embodiment hereinbefore described. slidingly mounted in this arcuate guideway is a rib 83 extending laterally from a wiping member 8:": which corresponds to the member 25 of the first embodiment, this wiping member being provided with a single tack-guiding passage 86 thorugh which an upper-fastening tack is driven into the shoe. Extending from the wiping member 85 is a lug 8'! which lies in a recess 89 in the part II. The member 85 is further controlled by a spring 9| mounted in a recess 93 in the part 1i, this spring holding the member normally in a position determined by engagement of the lug 87 with one wall of the recess 89, while permitting it to swing heightwise of the shoe about the axis 8| in response to pressure of the shoe thereon. It will be understood that a portion of the member 85 is confined between guiding faces on the parts TI and 13, as will be evident by reference to Fig. 9.

Each wiping member 85 has formed in it a straight guideway 95 in which is slidingly mounted an end-wiping member 91 corresponding in location and function to the member 31 of the first-described embodiment, this wiping member having an inwardly curved edge 99 which is continuous with the curved edge l!!! of the wiping member 85 when the parts are in their normal positions. The member 97 is yieldable laterally of the shoe relatively to the member 85 against the resistance of a spring lll3 which lies at one end in a bore H15 in the member 91 and abuts at the other end against a screw I01 in the extending into a slot HI in the member 85, the

pin normally engaging the member-85 at one end of the slot, as illustrated in Fig. 7.

Each or the wiping members 91 is normally prevented from yielding laterally of the shoe by a roll H3 which is mounted in a recess in the member and is held normally in wedging engagement with one wall of the guideway Q5 and a relatively inclined wall N5 of the recess in which the roll is mounted by means of a, spring Ill lying in a bore ll9'in the member 91, this spring engaging the roll at one end and an abutment screw |2I at the other end. Slidingly mounted in the member ill is a pin I23 one end of which engages the roll III-l and the other end of which is arranged to engage a similar pin in the opposite wiping member as the wipers are closed inwardly over the shoe bottom. It will be un derstood that upon such engagement of the two pins with each other, when the wipers have nearly completed their inward movements over the shoe bottom, the end wiping members 9'! are unlocked so that they are permitted to yield against the resistance of the springs I03 as the other portions of the wipers complete their inward movements. In this embodiment of the invention the members 91 are thus more readily yieldable in' rectilinear directions than, they would be if pivotally mounted in the manner of the wiping members 37 of the first embodiment, because their pivots if they were so mounted would necessarily occupy comparatively unfavorable positions. It will be understood that in response to resistance of the shoe the wiping members 85 and 91 may swing heightwise of the shoe about the axes 8| in the same manner as the corresponding wiping members of the construction first described.

In the construction shown in Figs. '7, 8 and 9 each member H has in it only a single tack and driver-guiding passage I25 (Fig. 9) in alinement with the passage 86 in the wiping member 85, the

tack being supported in this passage in position to be driven by means of a spring i2! which is fastened to the member 'll and extends into the passage H5.
